Omni-Freeze® technology features specially shaped flat yarns that facilitate the release of heat and feel cooler to the touch. It's not exactly magic, but when you're coolin' out on a blazing hot day, you might think it is. Add in UPF 50 sun protection to repel UV rays and throw in a cozy comfort stretch fabric and you've got the perfect recipe for beating the heat on the summertime streets - even if those streets are made of dirt and grass.
